4 -8=9-6X
Move -6X to the other side, sign changes from -6X to +6X.
4X+6X-8=9-6X+6X
4X+6X-8=9
10X-8=9
Move 8 to the other side, sign changes from +8 to -8.
10X-8=8=9+8
10X=17
divide by 10 for both sides
10X/10=17/10
X=17/10 or X= 1 7/10
Answer: X=17/10 or X= 1 7/10
F(4) = 7+4(4-1)
f(4) = 7+4(3)
f(4) = 7+12
f(4) = 19
The forth term is 19
f(40) = 7+4(40-1)
f(40) = 7+4(39)
f(40) = 7+156
f(40) = 163
The fortieth term is 163
